- Twist Crunches:
Once you get used to the regular crunches, modify the basic crunch to get an even more effective tummy exercise.
How To Do
Lie down on the floor with your hands behind your head.
Bend your knees as you would do in crunches, keeping your feet on the floor.
You have to lift your upper torso while performing crunches. But, in twist crunches, you have to lift just your right shoulder towards the left, keeping the left side of your torso on the ground.
Again alternately, lift your left shoulder towards the right, keeping the right side of your torso on the ground.
Repeat 10 times.
